Cut Fabrics

1. Sew together a cream tone-on-tone 2-1/2" square and a green tone-on-tone 2-1/2" square to make a chimney segment (Diagram 1). Press seam toward green tone-on-tone. The segment should be 2-1/2x4-1/2" including seam allowances. Repeat to make a second chimney segment.

2. Referring to Diagram 2, sew together chimney segments, two cream tone-on-tone 3-1/2x4-1/2" rectangles, and one cream tone-on-tone 4-1/2x8-1/2" rectangle in a row to make a chimney unit. Press seams toward cream tone-on-tone rectangles. The chimney unit should be 18-1/2x4-1/2" including seam allowances.

6. Sew together door unit, a solid cream 2-1/2x10-1/2" rectangle, and window unit to make a house unit (Diagram 6). Press seams toward solid cream rectangle. The house unit should be 18-1/2x10-1/2" including seam allowances.

7. Referring to Diagram 7, sew together chimney, roof, and house units to make block center. Press seams in one direction. The block center should be 18-1/2" square including seam allowances.

Assemble Hidden Square Blocks

2. Place one strip set right side up on your work surface with the cream tone-on-tone strip at the top. Top with a second strip set right side down and red print strip at the top (Diagram 10). Cut layered strip sets into six 3"-wide layered segments. Do not separate layers.

4. Sew a layered segment along one pair of long edges to make a block unit (Diagram 11; note that red print in upper layer is still at top). Press seam in one direction. The block unit should be 5-1/2x6-1/4" including seam allowances. Repeat to make 42 block units total.

5. Lay a block unit on work surface with wrong side up and red print squares in the upper right-hand and lower left-hand corners. Align the 45° angle of the acrylic ruler with left edge of block unit. Referring to Diagram 12, slide ruler up or down until its right-hand diagonal edge is 1/4" from seam intersection; use a pencil to draw a diagonal line on block unit. Repeat with remaining block units.

6. Layer a marked block unit atop a green tone-on-tone or green floral 5-1/2x6-1/4" rectangle; pin. Sew together with two seams, stitching 1/4" on each side of drawn line (Diagram 13). Cut apart on drawn line to make two triangle units. Press each triangle unit open, pressing seam toward green tone-on-tone or floral, to make two hidden square blocks. Each block should be 5-1/2" square including seam allowances.

2. Sew together blocks in each row of top section. Press seams in directions indicated on Quilt Assembly Diagram. Join rows; press seams in one direction. The top section should be 50-1/2x15-1/2" including seam allowances. Repeat to make bottom section.

3. Sew together blocks in rows in left- and right-hand units of center section. Press seams in directions indicated. Join rows; press seams in one direction. The units should be 15-1/2x20-1/2" including seam allowances.
